(PDL) (NASDAQ: PDLI) today announced that two inventors of the company's patented breakthrough antibody technology have been named as a top-three finalist for the European Patent Office's highly prestigious 2014 European Inventor Award in the "Non-European Countries" category.

Two blockbuster cancer drugs, Avastin® and Herceptin®, currently marketed by Genentech and Roche, are among them. The breakthrough technology was developed in the late 1980s under Dr. Queen's leadership while he and Dr. Selick worked together at biotechnology company, Protein Design Labs—now called PDL BioPharma. PDL BioPharma now manages the portfolio of patents referred to as the Queen et al. patents which underlie more than $15 billion per year related to the sale of the licensed products that use this technology.

Dr. Queen is now president of the biotechnology company, Galaxy Biotech, LLC; and Dr. Selick is now chief executive officer of Threshold Pharmaceuticals, Inc. Dr. Selick also serves on the board of directors of PDL, a position he has held since 2009.

"PDL's breakthrough antibody technology, invented by Drs. Queen and Selick, has dramatically impacted the lives of many patients and their families and continues to today, so it is heartening to see that the European Patent Office has chosen them as a finalist for this prestigious award. We would like to offer heartfelt congratulations to Drs. Queen and Selick on this important and well deserved nomination," stated John P. McLaughlin, president and chief executive officer of PDL BioPharma.
